FILLING CLAMIPIN'G AND PAaTING MEANS FORYLOOMS.

Application filed July 16,

To all 207mm it may concern:

Be it known that I, ALoNzo E. RHOADES, a citizen of the United States,residentof Hopedale, county of Worcester, State of Massachusetts, haveinvented an Improve ment in Filling Clamping and Parting Means forLooms, of which the following description, in connection with the accmpanying drawing, is a specification, l ke characters on the drawingrepresenting llke parts. p This invention relates to automat1c fillingreplenishing looms wherein the running filling is replenished prior tocomplete exhaustion and wherein the old or spent filling 1's partedbetween the cloth and the shuttle by a clamping and parting meansmounted upon a carrier, such as the usual swinging shuttle feeler, so asto be moved bodily rearwardly and forwardly or toward and from the lay.Q r The object of the invention is'to provide a construction in whichthe operation of the filling clamping and parting device is secured by astriker arm movable withthe filling carrier support commonly provided inthis type of loom and which acts to close the filling clamping andparting device when in operative position and which is yieldinglymovable with respect to -the filling carrler support upon the occurrenceof any abnormal resistance. v p

The object of the intention is further to provide a construction of thischaracter in which the striker arm is mounted in a housing on the sideof the filling carrier support and which thus presents a simple andeffective construction which may readily be added to existing looms. I

These and other objects and features of theinvention will appear morefully from the accompanying description and drawings and will beparticularly pointed out in the claims.

The drawings illustrate the invention'as embodied in a preferred form intheswell known Northrop type of automatic filling replenishing loom..The invention in some respects is an improvementupon the-comstrfuctionillustrated described in my prior application No. 469,599,filed May 14, 1921. r

In the drawings:

Fig. 1 is a transverse section of a portion of an automatic fillingreplenishing loom Specification of Letters Patent. P t ted M 514, 1 22;

1921. Serial No. 485,155.

with a preferred form of the present'ii'iven tion embodied therein, onlythose parts be-" ing illustrated which are necessary to the disclosureof the invention.

Fig. 2 is a view similar to Fig. 1 with many of the parts therein shownomitted and showingthe filling clamping and part ing device inpositionready to be closed upon the filling.

Fig. 3 is a front end elevation partially in vertical cross section ofthe construction shown in Fig. 2. v The construction and operation ofthe automatic filling replenishing loom herein illustrated being wellknown and familiar to those skilled in the-art, it will he neces sary todescribe in detail only-'those'features" and their operation immediatelyconcerned Wlth the pr invention.

The loom frame 1 supports the magazine or hopper 2 containing the supplyoffr'esh filling carriers herein-shown as bobbins '8;

hen the running filling in the shuttle 4011 the lay 5 has becomesubstantially exhausted,

indication of that fact I is transmitted through a well known. mechanismto the rod or rock shaft 6 which is thereupon rocked to' raisethe arms?and swing the shuttle feeler 8 rearwardly and at the samejtime to Iraise the dog 9 connected to the tran'sferrer 10 into the path of ahunter 11 on thelay;

If the shuttle is pro p'erly: boxed-allowing the shuttle feeler to passthe end: of the.

shuttle, then the bunter 11 strikingthe dog 9' swings. the transferrer10 downwardly forcing a fresh filling carrier 3 from its tion in themagazine down onto the-lay, and in this case into the shuttle '4;therebeneath simultaneously ejecting the substantially exhausted fillingcarrier from the lay. 1

When the fresh'filling carrier isinthe magazine 2. ready for transfer,it rests against an abutment 12 13 pivotedat 14:- in the k that, inorder topassout from the magazine, this support l3'must be swungdownwardly about its pivot. This filling carrier'support 3, which is afa'miliardevice'in this "type of loom, is rigidly connected to the pivot14 which extends to the front or opposite-side of the magazine and-isthere provided with posiand over a support magazlneframe'so anfupwardlyextending'arm 15.1 This arm slotted lug 19 projecting from the magazine2 and a helical spring 20 surrounds the pin between this lugand itsopposite head 21. Thus the pivoted or swinging support 13 is normallyheld in the position illustrated but may move or swing downwardlyagainst the tension of the spring 20 whenthe transfer or the freshfillingcerrier takes place. It thls device which 18 utilized to securethe operation of the filling clamping and parting device when, and' onlywhen, afresh filling carrier is transferred fromthe magazine to thelay.

The shuttle feeler 8 acts as -a carrier for the fillingclamping andparting device. In the form. illustrated the movable blade or member 22of this device is pivoted at 23 to the shuttle ieeler and swingsupwardly at its rearward or effective .end to close upon theco-operating elements of. the device and clamp part the filling. Therearward end of the shuttle feeler is also-at its lower edge beveledorinclined upgwardlyas shown at24=1to insurethefilling, extending from.

the {shuttle to the fell, being guided into the field of; action of .thefilling clamping and parting device.

The general operation is a familiar one. Upon the call for:fillingaeplenishment, .the shuttle vfeeler 8 is swung @rearwardly,' theI movable blade122 is swung to open position,

the filling clamping and parting device passes over the fillingextendingfrom the substantially exhausted fillingcarrier to the fell. The movableblade is then swung to closing position-parting and clamping thefilling, and then when the shuttle feeler swings forwardly the-clampedend of the filling is carried forwardly'so as to bring the fillingintothe Zpath of the usual temple thread cutter. I

The present invention is concerned particularly with the means for closing' th e fil 1- ing clamping and parting device.

' A housing 25 isirigidly secured to the side of thearm 15 which forms apart of the filling-carrier support 13. v This housing is held-in placeby a screw'26 passing through its lowerfiangedportionintothe arm 15 anda fulcrum stud 27 passing through the housing and serewedintothearm=1aLshaped striker arm 28 ispivotally .fulcrumed on the stud'27 with its'rearward end located in the housing and its foiwvard and laterally eretended end 29' projecting over the movable blade :22 of thefillingclamping and parting device when that device is in its rearwardoperative "position. An adjustable stop in the :form of 'a setsc-rew 30held in place alock nut '31 extends throu'gh th e top of the housingand-abutszthereariend of the striker arm .28. A' "longitudinally actinghelical spring 32 is enclosed in the housing and seated at its lower"end on the housing and at itsaupper zend'in asocket formed in alatrearend of the striker arm 28.. This helical spring 32-t-hus actsyieldin-gly'to hold the rearward end of the striker arm against thestop30. The striker armis thus enabled to yield against the tension ofthe spring with respectito the support upon the ocurrence of anyabnormal resistance. It is not an easy matter to assemble and adjust thefilling clamping and parting'device, the shuttle feeler, transferrer,etc. relatively .to each other, and this yielding :feature of thestriker arm enables any'inaccuracy in adjustment to be compensated forbythe relative yielding oi the striker arm and filling carrier. support inthe closing operation of the filling clamping and partingmeans. Theclosing movement otithe blade'22 is usually limited by a pin 34projecting laterally trom'the shuttle feeler through an opening '35-l'1'13li-il0 movable blade. After the movable blade has been closedtocausethe pin are) engage thewall of the opening '35, any furthermovement might act to'break or shear ofi the pin, but such furthermovement is pre vented in this case by theyielding ofethe striker-arm.

In order to .securethe opening of the :filling clamping and partingdevice when it moves .rearwardly to operative position. a

switch. cam mechanism is provided. For

this purpose abracket'armBB secured to the loom frame extends upwardlyand forwardly and at its upper. end-is provided with a stud 37 and astop lug 38;. Theswitch cam is in the form of an inclined flange 89formed on the rearward endof an arm 40 pivotedon the studBTnormallyerestingiby gravity on the lug 38. filling clamping and partingdevice is pro-.

vided with a laterally projecting pin 4d and the parts are so arrangedthat when the The movable blade 22-ofthe shuttle feeler swingsto'iorward position,

carrying the clampedand-parted filling end. this pin rides beneath theswitch cam 39 raising-the arm 40; which drops backxonto the lug-38 afterthe pinhas passed forward of it, to the position shown in Fig. 1.

When upon the call for filling-replenishment the shuttle :feeler swingsrearw'ardly, the pin 41 rides upon the forward -:Eaceot the switch camand :swings the movahle blade 22 to open position. p

The invention thus provides a simple and efieotive means for securing:the .-desired resultsin which thestriker arm and its connected partsform a sel-f contained structure which may readily be connectedtoexisting looms. p

Havingthus described my invention, what I claim as new and desire tosecurebyLetters Patent, is:

1. An automatic filling-replenishing loom comprising a lay, areplenishing magazine for the fresh filling carriers means fortransferring a fresh filling carrier from the magazine to the lay, afilling clamping and part ing device movable into position to receivethe running filling when the lay is in position for transfer, moved by afresh filling carrier upon its transfer from the magazine to the lay, ahousing secured to the side of the support, a striker arm piv'otallyfulcrumed in the housing and thus bodily movable with the support andhaving its forward end normally projecting over the filling clamping andparting device When the said device is in its rearward operativeposition, a stop on the housing limiting the downward movement of thestriker arm with respect to the support, a longitudinally acting helicalspring mounted in the housing and interposed between the housing and thestriker a filling carrier support arm and acting yieldingly to hold thestriker arm against the stop, the said striker arm thus moving with thesupport and acting to close the filling clamping and parting device whenin operative position but yielding against the action of the spring withrespect to the support upon the occurrence of any abnormal resistance. p

2. An automatic filling replenishing loom having the constructiondefined in claim 1 in which the portion of the striker arm extendinginto thesupport is provided with ALONZO E. RHoADEs.
